Yerp, looked everywhere, Rockauto, AZ, Oreillys, can't find the part number for the festoon base bulbs that are in my map lights.

Here's a picture:


It has flat sides and round sides. Weird.

 

i think the part number you are looking for is 2112. too bad you didn't live closer. i got all the lights i removed from my truck plus i got quite a few spare led lights left over from when i converted to led that should fit that socket.

you should check the end of the bulb by the wire. that is were the part number is. i just looked at mine and found 2122

 

I looked, didn't find a number, that's why I was asking. lol

So your's is 2122? I'll look to see if I can find any. I might convert to LED as my interior lights are too dim.

 

2122 or 2112. i got a few of both and they both look about the same as far as size and brightness goes. if you are going to buy led's i think i ordered 42mm leds and they fit good.
